Replace each instance of “Warehouse” in the rule Resources with “Warehouses”.
Create a subrule of “Resources”, called “Construction”. Give the subrule “Constructions” the following text:

As a Daily Action, a City may create a Construction as defined by the table below, with the Resource Cost being taken from any of their Warehouses.

If the rule Cranes and Fields has passed, create a new Rule called “Warehouses”, containing the following text:

Each Warehouse has a publicly tracked Blueprint, which is Shed by default. The maximum number of Resources a Warehouse can contain is defined by their Blueprint, and Warehouses are empty by default. The number of Warehouses a City owns and the Blueprint of each Warehouse is publicly tracked.
The list of Blueprints is as follows:
- Shed: May contain up to 5 Resources.
